"We wanted our whole house on smart switches. JJC Electric replaced every switch and dimmer with Lutron Caseta and set up the hub. They made sure every switch had a neutral wire. Now we control everything from our phones."
"Had a whole-house Generac generator installed by JJC Electric. The crew handled everything — concrete pad, gas line coordination, transfer switch, and the final hookup. We lost power twice since then and the generator kicked on instantly both times."
"JJC Electric wired our new hot tub with a dedicated 50-amp GFCI circuit and installed the disconnect switch exactly where the inspector wanted it. Passed inspection first try. Professional and by the book."
